1. Yes. Even with the bugs (which seem to be fewer and further-between compared to 360/PS3), I can't put this game down. 2. Not yet, but there are lots of community mods already out that fix a lot of quest bugs and the like, not to mention great gameplay mods. 3. Longer. Twice as many locations, and 163 quests vs 100 in FO3. In short, New Vegas will make you hate Fallout 3 and think it was shitty, if you didn't already.
